Thanks for your prompt reply.
(require (lib "gl-unsafe.ss" "sgl"))
(glGetFloatv 'GL_MODELVIEW_MATRIX)
gives me the error
dynamic-require: name is not provided: gledgeflagpointer by module:
|,C:\PROGA~1\plt\collects\sgl\gl-prims|
I am not sure what that means but gl-unsafe.ss requires
gl-wrapper-helper.ss. When I look in gl-wrapper-helper.ss it has a line
at the top that says
(define path '(lib "gl-prims.ss" "sgl"))
I did a search and there is no gl-prims.ss anywhere on my computer, least
of all in the sgl folder. There is a gl-prims.c and gl-prims-unsafe.c but
that's it.
